remove R=301 if you do not want the actual url to be rewritten in the browser and only forward on the request behind the scenes

If I remove R=301, it gives me internal server error. But this line is placed at the bottom of my htaccess file. So far this answer is working, I just don't want it to show in the browser URL that it's being redirected
